PROBLEM TO BE SOLVED: To reduce the increase in cost of an electric motor and the number of man-hours of maintenance such as replacement of the electric motor.SOLUTION: A range hood includes: a box-shaped body 2 above a cooking device 1; an impeller casing 3 inside the body 2; an impeller 4 provided inside the impeller casing 3; an electric motor 6 having a rotary shaft 5 for rotating the impeller 4, at the impeller casing 3 or the body 2; an orifice 22 provided at the impeller casing 3; a suction port 9 provided below the body 2; and an oil collection mechanism part 10 inside the body 2. The range hood can be acquired in which the oil collection mechanism part 10 and the impeller 4 are provided at the rotary shaft 5, the oil collection mechanism part 10 and the impeller 4 are provided at the rotary shaft 5 of one electric motor 6, the oil collection mechanism part 10 and the impeller 4 rotate at the same rotational frequency of the rotary shaft 5, and the increase is reduced in cost of the electric motor 6 and the number of man-hours of maintenance such as replacement of the electric motor 6.SELECTED DRAWING: Figure 1 |
